Oh, NOW I get it...

Ever since I first saw the trailer, I've been trying and trying to figure out how anyone thought it was a good idea to remake Footloose. And then, how anyone thought it would be a good idea to add some kind of explain-it-all backstory about the dance ban. But all that thinking was not for naught. I've figured it out: it's an allegory for the run-up to the Iraq war.
